Corn plastics: tips on alternative risks in the chemical plastics industry

Abstract: corn plastics have attracted widespread attention because of its dual effects in energy and environmental protection. The birth of "one-step" technology has changed the fate that corn plastic cannot be widely used due to its high cost, which will directly threaten the market position of the chemical plastics industry. The application industries of corn plastics are mainly in the packaging industry, plastic industry, agricultural mulching film, etc., and these industries are an important part of the plastic industry. No matter whether corn plastic will eventually replace chemical plastics or coexist with it, it will be a small blow to the chemical industry, which is not as suitable for the biological material industry as the universal experimental machine

and other medical equipment at the second Northeast Asia Expo held in Changchun, Jilin Province, a technology developed by Shanghai Tongji University to produce plastic from corn has attracted widespread attention because of its dual effects in energy and environmental protection

"corn plastic" does not pollute the environment. This kind of polylactic acid, commonly known as "corn plastic", can be decomposed by microorganisms in nature and eventually become carbon dioxide and water, which does not pollute the environment. It can also be applied to farmland as organic fertilizer to become plant nutrients, and is considered to be the terminator of "white pollution"

at present, the transparent and low-cost film plastic bags widely used in the market are mostly PVC (polyvinyl chloride) materials, which will melt when heated and release toxic and harmful substances. Scientific research results show that modern women are more and more likely to suffer from breast cancer. One of the reasons is that more and more "plasticizers" and other ingredients enter the abdomen indirectly, which makes hormones and other endocrine disorders. Moreover, traditional plastics, based on oil, not only consume resources, but also cannot be degraded, becoming a "white pollution" that threatens environmental protection

corn plastic uses corn and straw as raw materials, and lactic acid is obtained through microbial fermentation. Then lactic acid is polymerized to obtain biodegradable polymer material - polylactic acid. "Corn plastic" will naturally degrade into carbon dioxide and water after being buried in the soil for three months, half a year or a year. In addition, it also has the advantages of wear resistance and air permeability, which can comprehensively replace chemical plastics. It is regarded as the "fourth type of new materials" after metal materials, inorganic materials and polymer materials

the price is close to that of chemical plastics. At present, only one company in the United States can produce polylactic acid on a large scale, and the price per ton is about 3000 US dollars. In China, such a high price is unacceptable to the market. After eight years of research and one year of industrial scale-up, researchers have obtained ideal production costs through the "one-step" preparation of polylactic acid. In the "one-step process", lactic acid is synthesized into polylactic acid particles, and the production cost is greatly reduced. The ex factory price is about 10000 yuan per ton, which is close to the price of chemical plastic particles. Therefore, "corn plastic" has the conditions for popularization, application and industrialization

chemical plastics will be completely replaced. Some experts in the industry predict that corn plastics will fully replace chemical plastics within five years. Coupled with the degradable and environmental protection characteristics of corn plastics, technical workers in the current application field therefore take the maximum value of repeatability uncertainty in the three calibration points as the repeatability weight (1000N): u4=0.032%, and the indicators of technology and product characteristics have reached the level of chemical plastics

at present, an industrial prototype of "corn plastic" with independent intellectual property rights has been formed in Shanghai. This year, a production scale of 100 tons of "corn plastic" will be formed, and next year, a production line of more than 1000 tons will be formed

UnionPay analysis:

the birth of "one-step" technology has changed the fate that corn plastic cannot be widely used due to its high cost, which will directly threaten the market position of the chemical plastics industry. The application industries of corn plastics are mainly in the packaging industry, plastic industry, agricultural mulching film, etc., and these industries are an important part of the plastic industry

from the perspective of cost, the price of oil has been rising, while the price of corn has been stabilizing. From the perspective of energy, oil is a non renewable resource, while corn is a renewable resource. From the perspective of the market, although corn plastic is still in the stage of small-scale promotion, those who invest in the corn plastic industry are all powerful multinational enterprises, and their influence and economic strength are beyond doubt. With their driving benefits, corn plastic will become the fastest growth point of the plastic industry. In any way, corn plastic has the capital to replace chemical plastics

on the contrary, whether corn plastic eventually replaces chemical plastics or coexists with it, it will be a big blow to the chemical industry. UnionPay believes that with the continuous development of corn plastics in the packaging industry and the continuous improvement of the downstream industrial chain, corn plastics will inevitably find a living space in the market and endanger the chemical plastics industry. First, press the "return" button. Therefore, banks should strictly control the credit of the chemical plastics industry and pay close attention to the development trend of the industry. It is expected that the short-term credit of the industry will not be greatly impacted for the time being, However, the risk of medium - and long-term loans is relatively high, and it is suggested to shrink moderately
